Ok, I have some answers: 1. Logger works correctly, I can successfuly output message to the system log and read it after wards 2. Contents of /proc/net/netfilter/nf_log are: root@LEDE:/# cat /proc/net/netfilter/nf_log 0 NONE (nfnetlink_log) 1 NONE (nfnetlink_log) 2 NONE (nfnetlink_log) 3 NONE (nfnetlink_log) 4 NONE (nfnetlink_log) 5 NONE (nfnetlink_log) 6 NONE (nfnetlink_log) 7 NONE (nfnetlink_log) 8 NONE (nfnetlink_log) 9 NONE (nfnetlink_log) 10 NONE (nfnetlink_log) 11 NONE (nfnetlink_log) 12 NONE (nfnetlink_log) 3. modprobe nf_log_ipv4 fails with error saying that module can't be found. I'll try to compile it and add to the system On 21-03-2018 12:59, Pablo Neira Ayuso wrote: > What does > > cat /proc/net/netfilter/nf_log > > say there? > > You may need to: > > # modprobe nf_log_ipv4 -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
